Biorefineries are facilities that turn plants into useful products like biofuels and biomaterials. Different types of biorefineries exist, based on the materials they use. Some use crops like corn, wood, or algae, while others use different generations of biomass. Integrated biorefineries combine different technologies to use multiple materials and make various products. This is challenging because each material is unique. Scientists study different ways to convert these materials, like using heat, biology, or chemicals. They also develop tools to design sustainable biorefineries that are good for the environment and the economy. Integrated biorefineries are a promising approach to make the most of different materials and create valuable products.
